Gravitation

The earth is moving on an elliptical path, whose one focus sun is situated as shown in

figure. If AS = $r_{min}$ and SB = $r_{max}$ , the sun and earth system obey the Kepler’s law, the

square of time-period is directly proportional to

$(r_{max})^3$

$(r_{min})^3$

$\left(\frac{r_{\min } r_{\max }}{r_{\min }+r_{\max }}\right)^{3}$

$(\frac{r_{min }+r_{max }}{2})^{3}$
